PREPARING TO WORK
– Loosen the handle (1). (Fig. 5).
– Turn the ring-nut (3) to obtain the desired chain
tension level (Fig. 5).
– Raise the bar and tighten the handle (1) securely
(Fig. 6).
The tension is correct when the drive links do not
slip out of the chain guides if you hold the chain in
the middle of the bar (Fig. 7).
Loosen the brake by pressing both the switch
and the safety button. Using a screwdriver, run
the chain along the guides to check that it moves
smoothly.
3. CHECKING THE CHAIN BRAKE
This machine is equipped with a double braking
system that intervenes in two situations:
a) When the switch lever is released, a brake
is automatically activated that slows and stops
chain movement, in order to prevent the risk of
injury should the chain continue to turn after it
has been switched off.
b) In the event of a kickback while working,
following an irregular contact of the tip of the
bar, with a brusque upward movement that
causes the hand to strike the front guard. In
this case, the brake blocks chain movement
and must be released manually in order to dis-
engage it.
This brake can be operated manually by pushing
the front guard forward. To release the brake, pull
the front guard towards the handgrip until you hear
a click.
To check that the brake works efficiently, proceed
as follows:
– Start the engine by holding the front handgrip
and push the front hand guard forwards with
your thumb (towards the bar).
– When the brake is engaged, release the trigger
switch.
The chain must stop as soon as the brake is en-
gaged.
WARNING!
the chain brake does not function correctly
and have it inspected by your dealer.
Do not use the machine if

bio­degradable. The use of mineral oil or engine oil
can have a serious impact on the environment.
It is essential that you use good quality oil to lubri-
cate the cutting parts effectively.
Used or poor quality oil does not guarantee good
lubrication and reduces the duration of the chain
and bar.

are not compatible.
– Always handle and connect electric cables
in dry conditions.
– Keep electric sockets or cables away from
wet and damp areas (e.g. puddles or wet
ground).
The quality of the extension leads must be no less
than H07RN-F or H07VV-F, with a minimum sec-
tion of 1.5 mm and a recommended maximum
2
length of 30 m.
To avoid overheating, do not keep the extension
lead rolled up during use.
DANGER!
